Guidelines for Maintenance of Aging Water Pipes
Break failure patterns are investigated by applying a new methodology based on Proportional hazards and Poisson-type models. Application on two water distribution systems of North-Eastern...

Reviewing for Potential Failure
The key to preventing structural failures is to examines them and develop systematic techniques for avoidance. One, called contingency analysis, starts with a what if process to decide...

Available Compaction Equipment
When discussing available compaction equipment we must keep in mind the purpose of compaction. Compaction is the art of artificially increasing the density or increasing the unit weight...

Rapid Assessment of Seismic Vulnerability
The choice of a seismic damage assessment method depends fundamentally on how the assessment will be used, but always involves definition of the expected ground motion and the structure...

ATC Methodology and Data for Rapid Assessment of Seismic Vulnerability
Recently developed Applied Technology Council (ATC) methodology and data provide a technical basis for rapid assessment of structure seismic vulnerability. Methodology developed under...

Techniques for Estimating Earthquake Probable Loss for Buildings and Contents
The probable maximum loss (PML) is useful for quantifing the seismic risk exposure of a facility and for rational decision making regarding earthquake insurance and seismic strengthening...

Guide to Investigation of Structural Failures
Prepared by the Research Council on Performance of Structures of ASCE. This report contains guidelines for conducting an investigation into the causes...

Record High Rise, Record Low Steel
The Bank of China, under construction in Hong Kong, will be the world's fifth tallest building. In spite of the extraordinary codes for that city�high winds, and high live...

Harmonic Vertical Pile Response in Non-Homogeneous Medium
This paper describes the application of the boundary element method to determine the steady state response of vertically loaded floating piles in a non-homogeneous medium in which the...

Offshore Platforms Subjected to Wave Forces
The dynamic analyses of offshore platforms are mostly based on the lumped mass matrix method in the frequency domain. Although the approximations involved in the lumped mass matrix method...

Probabilistic Limit States Design of Moment-Resistant Frames Under Seismic Loading
This paper focuses on the development of a methodology for the optimal probabilistic limit states design of seismic-resistant steel frames. A mechanism for allowing the designer to include...

Some Applications of Fourier Series in Structural Optimization
This paper discusses the application of the method of truncated Fourier series to problems of structural optimization. It begins with a discussion of the range of the method which has...

Structural Optimization Under Conditions of Uncertainty, with Reference to Serviceability and Ultimate Limit States
Probability concepts and methods are rapidly gaining ground in the search for more rational approaches to structural optimization. Under conditions of uncertainty, the risk of unfavorable...

Reliability Constraint on Optimum Design
The purpose of the paper is to emphasize the importance of the probability concern on optimum design work. The probability of failure of the structure can be considered as one of the optimum...

The Effects of P-Delta and Semi-Rigid Connections on Response Behavior of Inelastic Steel Frames Subjected to Cyclic and Seismic Loadings
A numerical method is presented for analyzing semi-rigid connected steel frames subjected to various time-dependent excitations with consideration of damping, nonlinear material behavior...

U.S. Bureau of Reclamation Use of Risk Analysis
The United States Bureau of Reclamation (USBR) has been using risk analysis techniques in assessments for management decisions. Before presenting USBR practice and experience, the paper...

Factory Chic
Developers of the International Design Center of New York have recently spent $163 million to convert an unused chewing gum factory and a former battery plant into a showcase for New York...

Computer Assisted Pavement
In Rancho Palos Verdes, Calif. a 4,300 ft. long test installation of the Contained Rock Asphalt Mat (CRAM) Pavement System is expected to have a 50 year life. It cost a third less than...

Avoiding Cracks in Brickwork
Many aspects of movement and differential movement have been discussed. However, other movements and effects of movement that have not been discussed may also affect the performance of...

A Study of Exterior Facades?Problems and Solutions
